Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The visceral bone in the snout of swine that strengthens it for the rooting behavior of pigs.






2. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






3. Bones formed in the soft organs (viscera); examples include the os penis - the os cordis - and the os rostri.






4. One of the irregular bones of the spinal column.






5. Paired sesamoid bones in the legs of horses; located in the large digital flexor tendons behind the fetlock joints.






6. The outer layer of a bone that is composed of compact bone.






7. The cranial portion of the dorsal body cavity formed from several skull bones; it houses and protects the brain.






8. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






9. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






10. The paranasal sinus in the sphenoid bone; only present in horses.






11. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






12. The most proximal bony structure of the pelvic limb; also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.






13. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






14. A bone of a digit (finger or toe). Pl. - phalanges.






15. The group of vertebrae located dorsal to the abdominal region.






16. The large metacarpal and metatarsal bones (III) of the horse.






17. The process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal.






18. The last - most caudal sternebra; the _____ process.






19. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






20. The bones of the neck portion of the spinal column.






21. A thin bone located beside the tibia in the lower leg region of the pelvic limb. It is a complete bone in the dog and cat - but only the proximal and distal ends are present in horses and cattle. It doesn't support any appreciable weight - but acts a






22. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






23. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






24. Blood cell production; usually occurs in red bone marrow.






25. A lateral - projecting process of a vertebra.






26. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






27. One of two small sesamoid bones located in the proximal gastrocnemius muscle tendon just above and behind the femoral condyles of dogs and cats.






28. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






29. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






30. A skull bone; one of the external bones of the face. It is the lower jaw - the only movable skull bone - and contains all of the lower teeth.






31. Skull bones that are part of the internal bones of the face; also known as the nasal conchae. Four thin - scroll - like bones that fill most of the space in the nasal cavity.






32. A hinge joint in which one articular surface swivels around another; the only movements possible are flexion and extension.






33. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






34. The 'horn core' of horned animals; a process of the frontal bone. The hollow cavity within this process is continuous with the frontal sinus (the paranasal sinus of the frontal bone).






35. A rib whose costal cartilage joins the costal cartilage of the rib ahead of it instead of directly joining the sternum.






36. Skull bones that are part of the internal bones of the face; support part of the lateral walls of the pharynx.






37. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






38. A slightly movable cartilaginous joint - such as the pubic symphysis.






39. The joint movement that decreases the angle between two bones.






40. The socket portion of the ball - and - socket hip joint; it is formed at the junction of the ilium - ischium - and pubic bones of the pelvis.






41. Large process of the fibular tarsal bone that projects upward and backward; commonly referred to as the point of the hock. Site of attachment of the gastrocnemius (calf) muscle and equivalent to the human heel.






42. The smooth joint surface of a bone that contacts another bone in a synovial joint.






43. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






44. The vertebrae of the pelvic region; fuse to form a solid structure which forms a joint with the ilium called the sacroiliac joint.






45. The joint movement whereby an extremity is moved away from the median plane.






46. Incoordination; animals with this make jerky - spastic movements.






47. The type of bone formation whereby bone grows into and replaces a cartilage model; this is the method by which most bones form in a developing fetus - starting with cartilage 'prototypes' that are gradually replaced by bone. It is also the means by w






48. The joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans.






49. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.






50. The first - most cranial sternebra.
